Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated Webalizer packages fix vulnerability
Advisory ID: RHSA-2002:254-05
Issue date: 2002-12-04
Updated on: 2002-12-04
Product: Red Hat Linux
Keywords: DNS resolver buffer overflow flaw:buf
Cross references:
Obsoletes: RHSA-2001:140
CVE Names: CAN-2002-0180
---------------------------------------------------------------------
1. Topic:
Updated Webalizer packages which fix an obscure buffer overflow bug
in the DNS resolver code are available for Red Hat Linux 7.2.
2. Relevant releases/architectures:
Red Hat Linux 7.2 - i386, ia64
3. Problem description:
The Webalizer is a Web server log file analysis program which produces
detailed usage reports in HTML format.
A buffer overflow in Webalizer versions prior to 2.01-10, when
configured to use reverse DNS lookups, may allow remote attackers to
execute arbitrary code by connecting to the monitored Web server from
an IP address that resolves to a long hostname.
Red Hat Linux 7.2 shipped with Webalizer 2.01-9 which is vulnerable
to this issue.
Users of webalizer on Red Hat Linux 7.2 are advised to upgrade to
these errata packages which contain Webalizer version 2.01-09 with
backported security and bug fix patches.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only
those RPMs which are currently installed will be updated. Those RPMs
which are not installed but included in the list will not be updated.
Note that you can also use wildcards (*.rpm) if your current
directory *only* contains the desired RPMs.
Please note that this update is also available via Red Hat Network.
Many people find this an easier way to apply updates. To use Red Hat
Network, launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
60295 - Webalizer configuration file error
64392 - dns_cache missing, preventing webalizer from running
6. RPMs required:

You can verify each package with the following command:
rpm --checksig -v <filename>
If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
md5sum <filename>
